How about those Philadelphia Phillies?
Scarcely a month ago I would have never entertained posing such a question.
All the All-Star Break, the Phillies were 29-62 with the worst record in MLB.
Since the All-Star Break, the Phillies have the best record in MLB at 15-5. With tonight's 4-2 victory over the San Diego Padres, the Phillies have done the seemingly impossible - they have climbed out of last place in the NL East. Now it's the Miami Marlins who possess this ignominious distinction having lost 9 of their 10 games and 5-18 since the All-Star Break.
OK, the Phillies aren't going to play baseball in October. But they can finish the season a whole lot better than they started it.
